In this guide, we’ll make further strides to learn all it takes to grow and take attentive care of the Rosso plant.

More About The Peperomia Rosso

Same as the Peperomia Polybotryra, this variety is also a cultivar and grows restfully without asking for too much. Native to the tropical parts of South and Central America, this houseplant prefers to grow under humid conditions with ample light access for about 10 hours or slightly more.The Rosso Peperomia is quite a compact plant that fits in a small pot and grows in a rosette pattern. It’s a mixed breed of Peperomia Marmorata and Peperomia Metallica.

On average, this plant reaches up to 8’ inches both in height and width if you give it the essential requirements it yearns for all through the seasons. During the blooming stage, it develops dark-green leaves that take the shape of a heart. A mature leaf would roughly be about 1 to 2 inches long. The leaves of the Rosso Peperomia have deeply-rooted veins and are attached to stalks with a thick-red tone. Other incredible peperomia varieties include:

If you walk into your closest gardening retail store, you might otherwise find this variety labeled as theEmerald Ripple Pepper or the “Radiator plant”, so don’t get caught up in the puzzle of confusion since they all mean the same thing.

Peperomia Rosso Caring Tips


Before you even get started with setting up a watering schedule, it’s worth noting that the rosette which this plant forms, is overly sensitive to water. So you want to water your Emerald Ripple Pepper directly on the soil so it drains straight to the roots. A black mold rot will begin to form on the crown (rosette), especially during winter if it gets into contact with water. This plant can’t handle severe conditions. So you can neither afford to leave the soil dry for too long nor drench it with too much water.

It has roots that are extremely feeble and can’t withstand drought conditions. They’re, on the other hand, prone to rotting hence you can’t overwater your Peperomia Rosso plant. To merge these two pointers together, you need to wait until the soil is moderately dry so you can water your houseplant again.

Give it the right amount of water it needs, depending on the size of the growing medium. Remember to use one that allows any excess water to pass through the drainage holes. The Emerald Ripple Pepper ideally needs to be watered in 3 even intervals (every 10 days) each month during spring and summer.


Every year during the end of spring, replace the soil since it usually holds high soluble salt levels after fertilizing your plant. Another effective way is to wet the soil thoroughly, without causing and damage to the rosette. You can use a mist spray bottle to clean the plant when it gets dusty during the warmer months.

If you’re looking to grow it indoors, trim down the watering intervals during winter since the freezing conditions usually make the hormones dormant. This houseplant needs soluble fertilizer, preferably 20-20-20 NPK since all the essential macronutrients—nitrogen, phosphorus, and potassium—are well-balanced.When the plant is in its growing stage, use diluted fertilizer twice every month and supplement it with homemade plant food once a month.

Using a natural remedy such as banana peels helps your plant absorb high levels of potassium which it needs to activate the essential enzymes and CO2 uptake during the photosynthesis process. Epsom salt is also rich in magnesium and sulfur which allows the plant to have glowing and healthy foliage throughout the year. The best time to fertilize your newly propagated Radiator plant is during spring and after its a couple of months old.

Soil & Transplanting

All plants in the Peperomia family grow fluidly in a well-draining potting mix with a solid volume to retain some bits of moisture. Succulents do well in a normal cactus mix or under the same soil requirements for Echeverias. Although it doesn’t necessarily need to be nutrient-dense, make sure the soil is porous enough to let the water drain fairly easily.

Remember to add equal portions of perlite and peat moss when preparing your plant’s potting soil. The Radiator plant, like most other succulents, is such a compact plant that grows evenly, so repotting won’t be a frequent thing to do. You only want to transplant it when it outgrows the first pot.

Another sign that suggests you need to re-pot your plant is if the roots begin to elongate further through the drainage holes. Be careful while carrying out this exercise not to cause any irreversible damage to any part of the root structure.

Light & Temperature

Owing to the fact that this is a tropical succulent, the Peperomia Rosso will seamlessly bloom under bright, indirect light. And since it’s mostly a houseplant, place it somewhere near a window or use grow lights to accelerate its photosynthesis process so the foliage can get thicker and greener much quicker. Give it access to partial shade because it can’t keep up with direct sun rays. This succulent also doesn’t yield anything solid if placed in a dark room. The leaves will begin to wane if it stays in a place with poor lighting.

With USDA hardiness zones 11 through 12, the Peperomia Rosso plant can tolerate the winter season and gets along so well with temperatures ranging from 10-25°C. It also prefers to be in a surrounding with reasonably high humidity levels, particularly slightly above 50%. Use a spray bottle to mist the plant if the humidity is low.

Grooming Tips

Trim it evenly to maintain its pattern and shape. You can also dust the plant off using a mist spray bottle and a soft cloth. The most suitable time to prune your Radiator plant is during the first few weeks of the spring season.

How to Propagate The Peperomia Rosso

The method for propagating your Peperomia Rosso is no different from that of other headline succulents. One of the easiest and most responsive ways for propagating this variety is using stem cuttings. For this method to work just fine, you need to:

  1. Use a sharp, sterilized knife to cut a long stem with a few healthy leaves from the mother plant.
  2. Leave the edge of the stem to dry out before planting it in the container.
  3. Dip the edge of the cutting in a sizeable rooting hormone portion, to level up the roots’ growth rate
  4. Use organic compost on the potting soil to help the cutting have a firm support base
  5. Gently moist the topsoil and place the growing medium under indirect, bright light.

Within 30 days, you’ll begin to see tangible results. Don’t use fertilizer on the baby Rosso until it’s about 6 months old.

Common Pests & Diseases

If you nurture your Emerald Ripple Pepper using the caring requirements it needs, you won’t need to worry much about serious diseases or pest attacks. If your plant is weak due to improper growing conditions, it’ll be prone to whitefly, mealybug, and spider mite attacks. To know if your plant is infested with mealybugs, lookout for any whitish coating on the stems or under-sides of the leaves.

The leaves might also become frail and faint if the plant isn’t getting the right temperature, light, and humid conditions. Too much watering will also cause the plant to have a mold coating and ultimately die off. You’ll also probably have to deal with fungus gnats due to overwatering. Use neem oil or any other insecticidal soap to get rid of insects that would leech off of your plant’s essential juices.

Radiator plants growing outdoors might also suffer from snail and slug attacks, especially during the cold period. In case this happens, a quick remedy would be to use liquid bait such as beer, iron phosphate, or salt to dehydrate and kill them. When you propagate or prune your Peperomia Rosso plant, make sure to sterilize the tools using isopropyl alcohol. If you use the tools without disinfecting them, you risk transmitting the newly propagated cuttings with bad bacteria and diseases that would make them have stunted growth.

Is The Peperomia Rosso Toxic?

Peperomias are one among the rare succulent houseplants that are entirely non-toxic. So you won’t need to panic about growing them with the reach of your kids or pets.

Peperomia Rosso Uses

Although the Peperomia Rosso can juggle as both an indoor and outdoor plant, it mostly fits to be an apartment accessory. So it would be more suitable to grow it as a houseplant somewhere on your office desk or bedroom’s windowsill. The only catch is you need permeable soil, a container with enough drainage holes, and well-lit space with moderately-filtered light.
